About this time I was subjected to a severe trial. If the Spirit of God rested upon anyone in meeting, and he glorified God by praising Him, some raised the cry of mesmerism; and if it pleased the Lord to give me a vision in meeting, some would say that it was the effect of excitement and mesmerism. Grieved and desponding, I often went alone to some retired place to pour out my soul before Him who invites the weary and heavy laden to come and find rest. As my faith claimed the promises, Jesus would seem very near. The sweet light of heaven would shine around me, and I would seem to be encircled by the arms of my Saviour, and would there be taken off in vision. But when I would relate what God had revealed to me alone, where no earthly influence could affect me, I was grieved and astonished to hear some intimate that those who lived nearest to God were most liable to be deceived by Satan. LSMS 136.1
According to this teaching, our only safety from delusion would be to remain at a distance from God, in a backslidden state. Oh, thought I, has it come to this, that those who honestly go to God alone to plead His promises, and to claim His salvation, are to be charged with being under the foul influence of mesmerism? Do we ask our kind Father in heaven for bread, only to receive a stone or scorpion? These things wounded my spirit, and wrung my soul with keen anguish, well nigh to despair. LSMS 136.2
